WordPress Plugin Development Part 2 | How To WordPress Development Tutorial 

Sir, you are a really amazing coder. You know how to deliver knowledge to others. Really enjoyed this video

Thank you for the video. Steps are very easy to follow. Instead of Header and Footer scripts i used it to create shortcodes for contact information like address, phone, and email to reuse on different places of the website. Now i'm building on top of it, i'm looking for a way to add new fields from the plugin page itself.

Thanks mate!

I’m not well known with Wordpress myself, that is why I’m watching this. But I imidiatly stumble over the fact that even if it is behind an admin panel it still is a huge code injection vulnerability. For an example you can say this is okay but be warned and look into code injection here. You should not be printing JavaScript unless you are absolutely 100 percent sure of what you are doing. For a plug-in example you could’ve picked a way better and more save example in my opinion, A simpele hello world page would’ve been sufficient.

Today I Develop My first Wordpress Plugin, Every One Should Watch This Video. Thank You

Where were you buddy ! I am into PHP Development since last 12 years and Wordpress code was always intimidating me. Watched some videos and they make it so tough to understand this simple plugin development process... But u... You are a gem.

@Joshua Herbison, please help me with the error, as I'm unable to find any Not able to see the textarea values on the site, on both header and footer in Wordpress 5.1 Here is the code : function learn_scripts_page() { //if($_POST['submit']){ if(array_key_exists('submit', $_POST)){ update_option('learn_header_scripts',$_POST['header_scripts']); update_option('learn_footer_scripts',$_POST['footer_scripts']); ?> Saved

function codeflash_scripts_page() { if (array_key_exists('submit_scripts_update', $_POST)) { alert('Hello! I am an alert box!!'); update_option('codeflash_header_scripts', $_POST['header_scripts']); update_option('codeflash_footer_scripts', $_POST['footer_scripts']); ?> Settings have been saved.

array_key_exists() expects parameter 2 to be array, null given in C:\xampp\htdocs\peoplecraft\wp-content\plugins\dummy plugin\index.php on line 35 how to fix this error

I love the videos. Thanks a ton

Can anyone help me.. I am very new to wordPress and php and I just copied the exact same code as below: Update Scripts on header and footer But it doesn't show any Site Scripts in the sidebar in dashboard. Any suggestions would be highly appreciated!!

Thanks Joshua Herbison for creating simple plugin development video. I am trying to new develop plugin, but a error irritate me. Error " Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'certificate-scripts_pages' not found or invalid function name in C:\xampp\htdocs ews\wp-includes\class-wp-hook.php on line 287 ". code : add_menu_page('Certificat Issue Setting','Certificate Options','manage_options','certificate-admin-menu','certificate-scripts_pages','',200); I am new in wordpress plugin development. Please help me

WordPress the worst php nightmare, laravel is the only reason why php is still alive there outside.

what does get_option do? also i kinda understand the array_key_exists checks for values submitted by the form/?

Great video, it's very helpfull. Can you create new video about using custom sql queries to own created database tables in Wordpress, thank you

Excellent video thank you for you efforts. I've have one issue when using this to add in my Google Analytics scripts, these functions are adding an extra back slash \ every time my 'UPDATE SCRIPTS' button is clicked. i.e. This is the google script an extra back slash after the equals of the src parameter as well as a few others? I can't see where they are coming from?

You are the best at simplifying the plugin dev process. Kudos!

why is it automatically adding \ in front of " and ' ??

Excellent course 06/06/2021

I don't understand the "wp_head", "wp_footer". It says "Fire the 'wp_footer' action. ". Why do we need search for the scripts in the source code , but not on the page. How do we check the event name which fires an action. May we get a list on wordpress?

why dont you give the code? I have an error and I cant double check.

Where is the source code available ?

super explanation and easy to understand thank you very much!

This is rwally usefull for me

I'm doing something slightly different, but your guidance has helped me get somewhere I'd have spend multiple days on trying to find the solution on my own, thank you.

Really thank you men

awsome! thank you so much. such a nice tutorial.

Hello Joshua, thanks for publishing this great tut. It really helped me a lot. Thank you for simplifying things out. I thought this was hard and complicated.

Great wideo , but i would also like to see how to save value from input type=checkbox , and imo You should show how to retrieve values and use it on frontend. Please Joshua, show it!

you are my teacher

Thanks you!! Can you add video instruct use vuejs (cli 3) to buid plugin wordpress .

Once again, great video, Josh. You cover admirably critical topics that is often left out by others. If one wants to customize their website, he/she is forced to spend significant money on pro features. Your videos help those who want to own their personalization. Thank you. !

Very helpful.

Good tutorial sir RESPECT from my side too , can u update me with plugin to add upload image settings in user menu page of admin dashboard. When user edit in uername label, he should able to upload profile picture .Its plugin about gravatar. (Now user can upload image through gravatar only.)Please help me if u can come up with some ideas ;will be really appreciated sir.

Thanks a lot, Joshua, its a great start video for plugin development. Thanks again, keep up the good work..!!

Hi Josh, thanks for the great tutorial! But could I have a slight more in depth explanation as to what updating the footer/header scripts would do?

Hi Joshua, I'm loving your videos- thank you so much for making these available! I wonder if I'm misunderstanding something on this video. Watching it, it seems to show that the scripts should be inserted into the header (or footer) , but NOT visibly part of the header/footer (e.g. you don't want your google analytics stuff visible in the footer). However, my header and footer scripts end up visibly in the header and footer. Just to make sure that I didn't do something funny in my code, I downloaded your file and installed it, with the same result: the scripts that I add are visible as part of the header/footer on my site. Is it possible that my version of PHP does something different with the print statement? I'm running a MAMP localhost with php 7.4.2 on IOS. Thanks again!!

Thank you! Great explanation, easy to understand, friendly and interesting speech. Several questions please: how is your sublime text configured? ( please tell about ssh upload and wp syntax support, may be other useful stuff ). Please give link to your plugin zip.

Thanks for the awesome stuff! You really deserve more likes and subscribers.

Thanx a million Joshua, I was looking for these videos for months! Amazing!

honestly one of the best ASMR vids, also educational

I'm agreed with Web By VJ Everyone must watch this video thanks a lot

Nice man! Thanks for sharing your knowledge

if(array_key_exists('submit_scripts_update',$_POST)) never happen, why? the submit line is :

Good evening sir, now solved my problem. Thanks for valuable wordpress tutorial series.

Hi, nice tutorial. Thank you! However I have a question. Will those field take actual scripts as input?

This is an excellent tutorial. At the end you mention “in the next video I’ll go into detail on how to add a sub-page to this menu option.” I couldn’t find adding menu sub-pages. Did I miss it or did you not do it?

I tried to duplicate what you had (including the corrections), but at 15:29, the entries in the text areas just disappeared when I clicked on UPDATE SCRIPTS, and the two variables were just null. Is there some update to WP or PHP in the last 2 years that broke that? I double-checked everything that you had on the screen. Is there a downloadable copy of this plugin that I can compare with mine?

Thanks sir Good Job one question is if there is a pre-defined classes or function in the code please explain it

Thank you for the tutorial series, Joshua. Can anyone point me to a resource on how you get your development environment setup? It looks like the changes being made are updating live to a wordpress site online - how do you set up the environment on your local machine like it is in the video?

Great tutorial, found it super useful. You are able to break it down really well unlike other tuts out there. Just to add and by no means do I think this is the best way to do implement this but I found on line 63 when printing to DOM it only outputs the string of text you entered in the textarea field. If you do something like this on line 63 print (""); it will wrap it in script tags. Its the only thing I found missing from this tutorial. Saying that I am not 100% how secure this is.

Very good explanation, can we download the source code?

Thanks You For Make This . I am From Cambodia . Videos So Clear

I have an issue here. When others plugins are installed, my new plugin wont show in dashboards, sidebar. I also changed number position to something unique and still have the same problem. Any advice?

end of the video you will show the header and footer scripts in page source but I can't, what was the issue in that? please suggest me

hi, i have a question, these options (header and footer scripts) are saved in some variables, so next time i visit the site will they still exist? Does the update_option save them in the database?
